Start here

Start from a house.

140 ready designs cover the Polish-market typology — single storey, attic, two storey; gable, hip, flat, shed roofs; none, one or two garage bays. Pick one, place it, and it's yours to redraw: placing replaces the design and nothing locks.

From catalogue to plot in four moves.

The Houses panel is a first-class view of the editor, not a dialog box. It appears with the select tool and nothing selected — the catalogue is the beginning, not an add-on.

01
Open the Houses panel

It appears with the select tool, nothing selected. 140 original designs, no third-party filler.

02
Pick a typology

Single storey, attic or two storey. Gable, hip, flat or shed roof. None, one or two garage bays.

03
Place it

Placing a house replaces the design in one move — and everything stays editable: walls, openings, roof, materials, garden.

04
Or bring your own

Open reads a *.webhome.json file, ?design=<url> opens a shared design, and ?fresh=1 / ?empty=1 start you clean.

Four ways in, one editor

Every door leads to the same house.

  • A different house every visit

    The app opens on a different design each time — the catalogue demos itself while you make coffee.

  • Placing replaces, nothing locks

    The placed house becomes your design: draw walls, cut openings, swap the roof, refurnish, replant.

  • *.webhome.json

    Save/Open exchanges real files — a design you can mail, archive, or version in git if that's your practice.

  • ?design=<url>

    A shared design opens straight from a link — silent sign-in if you're already in the castomo estate.

  • Clean-plot parameters

    ?fresh=1 and ?empty=1 when you want a clean start; ?quality= picks a render tier; ?reveal=0 skips the build-up. The URL is a remote control.

What you get, plain.

"Starting from zero is a hobby. Starting from 140 houses is a Tuesday."

— the Houses panel

Start from a house.
Redraw it.

140 ready designs, *.webhome.json, ?design= links — and every wall editable after.
